Compare a crystal lattice with a molecule. what does the formula unit al(oh)3 tell you about the compound aluminum hydroxide?

A crystal lattice is a solid in which the particles are arranged in a regular, repeating pattern.

A molecule is a discrete unit of atoms that is bonded together.

Many ions come together to form a crystal.

The formula unit of an ionic compound represents the smallest ratio of ions in the crystal.

The lattice of aluminum hydroxide has three OH- ions for every Al3+ ion.

Explanation:

any of those are right

it means there are 3 atoms of oxygen

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
